The DS3231 is an I2C real-time clock with internal temperature compensated oscillator, maintaining civil time to 1 s precision with nominal 2 ppm accuracy from 0-40 Cel. The basic functionality is exposed as a counter that is always running at 1 Hz. Much more functionality is exposed as driver-specific API, including the ability to translate between the time scale of the DS3231 and the time scale of the Zephyr uptime clock. This allows correlation of events in the system clock to UTC, TAI, or whatever time scale is used to maintain the DS3231. Signed-off-by: Peter A. Bigot <pab@pabigot.com>
